Unit 1 · Level 2 · Rules & checklists
Friction design
You beat temptation with distance, not strength. Trading apps are engineered the other way: one-tap orders, confetti on fills, push alerts at midnight, all sanding friction off the impulse trade. Friction design flips the game: add steps between you and the bad trade, remove steps between you and the good habit. The lazy path should lead somewhere safe.

What you get asked
Match the tweak to what it does
None of these need willpower after setup day. That's the signature of good friction design: one decision, permanent effect.
Trading apps ship confetti animations and one-tap orders. What are they optimizing for?
Most brokers earn per trade, directly or through order flow. Every design choice that makes trading feel like a game serves their revenue line, not your expectancy.
Design your setup so the good habit sits on the path of least ___.
Whatever is easiest is what tired-you will do. Make the easy thing and the right thing the same thing.
You keep chasing pumps from your phone at midnight. Which fix actually uses friction design?
The sincere promise is willpower in a trench coat. Real friction is structural: midnight-you simply can't place the order without getting out of bed.
Sum up friction design in one line:
The demons from League 1 never die, but they're lazy too. Ten seconds of friction defeats a surprising share of bad trades. 🐜
